LORENZ BOMMER, OF BROOKLYN, NEW YORK.

SPRING-HINGE.-

SPECIPICA'IION forming part of Letters Patent No. 383,554, dated May 29,1888.

Application filed May 1'7, 1867. Serial No. 238,448. (ModeL) To all whomit may concern.-

Be it known that I, LORENZ BOMMER, of Brooklyn, in the county ofKingsand State of New York, have invented certain new and useful Improvementsin Spring-Hinges, of which the following is a specification.

This invention relates to certain improvements in spring-hinges, bywhich a more reliable and stronger connection between the pintlesocketsof the hinge and the leaf attached to the door frame or casing isobtained, and by whicha better appearance isimparted to the hinge; andthe invention consists, first, of the combination of a leaf attached tothe door-frame and provided with pintle-sleeves made integral therewithwith pintle-sockets having an interior cavity and a lateral recessfitting over said sleeves.

The invention consists, secondly, ofthe co mbination, in a spring-hinge,of pintle-sockets having threaded ends or shanks with detach able andinterchangeable caps fitting over the ends or shanks of saidpintle-sockets.

In the accompanying drawings, Figure 1 represents a side elevation,partly in section, of my improved spring-hinge. Fig. 2 is a horizontalsection on line xx, Fig. 1; and Fig. 3 is a detail view of one of thepintlesockets, showing the recess for connecting it with the leafattached to the door-frame.

Similar letters of reference indicate corre sponding parts.

In the drawings, A represents the leaf of a doorhinge, which leaf isattached to the door frame or casing.

B represents the leaf attached to the door, said leaf being madeintegral with the spring inclosing barrel 0. The pintle D passes throughthe center of the spring-barrel O and the adjustable spring-sockets G ofthe same,

and through pintlesockets E, which are secured to pintle-sleeves a, thatare made integral with the leaf A, as shown in Fig. 2.

The pintle sockets E E are made of cast metal, provided with an interiorcylindrical cavity, 6, and a lateral recess, 6, as shown clearly inFigs. 2 and 30f the drawings. The recessed sockets e e are fitted overthe pintlesleeves a of the leaf A, so as to be rigidly secured thereto.The ends or shanks of the pintle-soekets E are screw-threaded andprovided with detachable caps F, of any suitable ornamental shape, whichcaps are screwed on the ends or shanks of the sockets E after the pintleD has been passed through the same and its ends rigidly attachedthereto. This is accomplished either by enlarging the end of the pintleD after it has been passed through the pintle-sockets or by attachingsaid pintle in any other manner to the pintle-sockets, so that it cannotmove up or down to change its position. In this manner a strong anddurable hinge is obtained by the rigid connection of the pintle-socketswith the pi utle-sleeves of the leaf attached to the door-casing, whilethe working loose of the ornamental tip, which is the great drawback inall hinges in which the ornamental tips are screwed on directly to thepintles, is entirely avoided, and the advantage gained that theornamental caps on the hinges can be at any time changed at a smallexpense, and that a great variety of ornamental caps can be kept instock and applied to the hinges according to the taste of the purchaser.

Having thus described n1yinvention,I claim as new and desire to secureby Letters Patent-- 1. The combination, in a spring-hinge, ofa leafattached to the door frame or casing, said leaf having pintle-sleevesmade integral therewith, pintle-sockets having interior cylindricalcavities and lateral recesses fitting over the pintle-sleeves of theleaf, and a pintle passing through said sleeves and sockets and beingrigidly attached to the latter, substantially as set forth.

2. In a spring-hinge, the combination of a leaf having pintle-sleevesmade integral therewith, pintlesockets having interior cavities andlateral recesses fitting over said pintlesleeves, a pintle passingthrough said pintle sleeves and sockets and attached to the latter, anddetachable caps applied to the screwthreaded shanks or ends of thepintle-sockets, substantially as set forth.

In testimony that Iclaim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.

LORENZ BOMMER.
